FIELD OF THE INVENTION

This invention relates to novel lactams having drug and bio-affecting properties, their pharmaceutical compositions and methods of use. These novel compounds inhibit the processing of amyloid precursor protein and, more specifically, inhibit the production of Aβ-peptide, thereby acting to prevent the formation of neurological deposits of amyloid protein. More particularly, the present invention relates to the treatment of neurological disorders related to β-amyloid production such as Alzheimer's disease and Down's Syndrome.

BACKGROUND OF THE INVENTION

Alzheimer's disease (AD) is a degenerative brain disorder characterized clinically by progressive loss of memory, temporal and local orientation, cognition, reasoning, judgment and emotionally stability. AD is a common cause of progressive dementia in humans and is one of the major cause of death in the United States. AD has been observed in all races and ethnic groups worldwide, and is a major present and future health problem. No treatment that effectively prevents AD or reverses the clinical symptoms and underlying pathophysiology is currently available (for review see Dennis J. Selkoe; Cell Biology of the amyloid (beta)-protein precursor and the mechanism of Alzheimer's disease, Annu Rev Cell Biol, 1994, 10: 373-403).

Histopathological examination of brain tissue derived upon autopsy or from neurosurgical specimens in effected individuals revealed the occurrence of amyloid plaques and neurofibrillar tangles in the cerebral cortex of such patients. Similar alterations were observed in patients with Trisomy 21 (Down's syndrome) and hereditary cerebral hemorrhage with amyloidosis of the Dutch-type. Neurofibrillar tangles and nonmembrane-bound bundles of abnormal proteinaceous filaments and biochemical and immunochemical studies led to the conclusion that their principle protein subunit is an altered phosphorylated form of the tau protein (reviewed in Selkoe, 1994).

Biochemical and immunological studies revealed that the dominant proteinaceous component of the amyloid plaque is an approximately 4.2 kilodalton (kD) protein of about 39 to 43 amino acids. This protein was designated Aβ, β-amyloid peptide, and sometimes β/A4; referred to herein as Aβ. In addition to its deposition in amyloid plaques, Aβ is also found in the walls of meningeal and parenchymal arterioles, small arteries, capillaries, and sometimes, venules. Aβ was first purified and a partial amino acid reported in 1984 (Glenner and Wong, Biochem. Biophys. Res. Commun. 120: 885-890). The isolation and sequence data for the first 28 amino acids are described in U.S. Pat. No. 4,666,829.

Compelling evidence accumulated during the last decade revealed that Aβ is an internal polypeptide derived from a type 1 integral membrane protein, termed β amyloid precursor protein (APP). β APP is normally produced by many cells both in vivo and in cultured cells, derived from various animals and humans. Aβ is derived from cleavage of β APP by as yet unknown enzyme (protease) system(s), collectively termed secretases.

The existence of at least four proteolytic activities has been postulated. They include β secretase(s), generating the N-terminus of Aβ, a secretase(s) cleaving around the 16/17 peptide bond in Aβ, and γ secretases, generating C-terminal Aβ fragments ending at position 38, 39, 40, 42, and 43 or generating C-terminal extended precursors which are subsequently truncated to the above polypeptides.

Several lines of evidence suggest that abnormal accumulation of Aβ plays a key role in the pathogenesis of AD. Firstly, Aβ is the major protein found in amyloid plaques. Secondly, Aβ is neurotoxic and may be causally related to neuronal death observed in AD patients. Thirdly, missense DNA mutations at position 717 in the 770 isoform of β APP can be found in effected members but not unaffected members of several families with a genetically determined (familiar) form of AD. In addition, several other β APP mutations have been described in familiar forms of AD. Fourthly, similar neuropathological changes have been observed in transgenic animals overexpressing mutant forms of human β APP. Fifthly, individuals with Down's syndrome have an increased gene dosage of β APP and develop early-onset AD. Taken together, these observations strongly suggest that Aβ depositions may be causally related to the AD.

It is hypothesized that inhibiting the production of Aβ will prevent and reduce neurological degeneration, by controlling the formation of amyloid plaques, reducing neurotoxicity and, generally, mediating the pathology associated with Aβ production. One method of treatment methods would therefore be based on drugs that inhibit the formation of Aβ in vivo. Methods of treatment could target the formation of Aβ through the enzymes involved in the proteolytic processing of β amyloid precursor protein. Compounds that inhibit β or γsecretase activity, either directly or indirectly, could control the production of Aβ. Advantageously, compounds that specifically target γ secretases, could control the production of A{tilde over (β)}. Such inhibition of β or γ secretases could thereby reduce production of β which, thereby, could reduce or prevent the neurological disorders associated with Aβ protein.

Definitions

As used herein, the term “Aβ” denotes the protein designated Aβ, β-amyloid peptide, and sometimes β/A4, in the art. Aβ is an approximately 4.2 kilodalton (kD) protein of about 39 to 43 amino acids found in amyloid plaques, the walls of meningeal and parenchymal arterioles, small arteries, capillaries, and sometimes, venules. The isolation and sequence data for the first 28 amino acids are described in U.S. Pat. No. 4,666,829. The 43 amino acid sequence is:

 1 Asp Ala Glu Phe Arg His Asp Ser Gly Tyr 11 Glu Val His His Gln Lys Leu Val Phe Phe 21 Ala Glu Asp Val Gly Ser Asn Lys Gly Ala 31 Ile Ile Gly Leu Met Val Gly Gly Val Val 41 Ile Ala Thr

The term “APP”, as used herein, refers to the protein known in the art as β amyloid precursor protein. This protein is the precursor for Aβ and through the activity of “secretase” enzymes, as used herein, it is processed into Aβ. Differing sectretase enzyme, known in the art, have been designated β secretase, generating the N-terminus of Aβ, α secretase cleaving around the 16/17 peptide bond in Aβ, and “γ secretases”, as used herein, generating C-terminal Aβ fragments ending at position 38, 39, 40, 42, and 43 or generating C-terminal extended precursors which are subsequently truncated to the above polypeptides.

The compounds herein described may have asymmetric centers. Compounds of the present invention containing an asymmetrically substituted atom may be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis from optically active starting materials. Many geometric isomers of olefins, C═N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomeric form is specifically indicated.

The term “substituted,” as used herein, means that any one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substituent is keto (i.e., ═O), then 2 hydrogens on the atom are replaced.

When any variable (e.g., R^(5b)) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-3R^(5b), then said group may optionally be substituted with up to three R^(5b) groups and R^(5b) at each occurrence is selected independently from the definition of R^(5b). Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

For example carbon 3 of lactam ring B Formula (I″) may exist in either an S or R configuration. Thus, an R or S configuration at carbon 3 in Formula (I″-3R) and (I″-3S) are considered part of the invention. Examples of such configuration include,

but are not intended to be limited to this example of ring B. When required, separation of the racemic material can be achieved by methods known in the art. Additionally when the carbon atom to which Q and R⁵ are attached is chiral, both the R and S configurations of the carbon atom are considered part of the invention.

The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

As used herein, “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutaric, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic, and the like.

The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, p. 1418, the disclosure of which is hereby incorporated by reference.

“Prodrugs” are intended to include any covalently bonded carriers which release the active parent drug according to formula (I) in vivo when such prodrug is administered to a mammalian subject. Prodrugs of a compound of formula (I) are prepared by modifying functional groups present in the compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compound. Prodrugs include compounds of formula (I) wherein a hydroxy, amino, or sulfhydryl group is bonded to any group that, when the prodrug or compound of formula (I) is administered to a mammalian subject, cleaves to form a free hydroxyl, free amino, or free sulfhydryl group, respectively. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of alcohol and acetamide, formamide, and benzamide derivatives of amine functional groups in the compounds of formula (I), and the like.

“Stable compound” and “stable structure” are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.

Synthesis

The compounds of the present invention can be prepared in a number of ways well known to one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. All references cited herein are hereby incorporated in their entirety herein by reference.

The novel compounds of this invention may be prepared using the reactions and techniques described in this section. The reactions are performed in solvents appropriate to the reagents and materials employed and are suitable for the transformations being effected. Also, in the description of the synthetic methods described below, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and workup procedures, are chosen to be the conditions standard for that reaction, which should be readily recognized by one skilled in the art. It is understood by one skilled in the art of organic synthesis that the functionality present on various portions of the molecule must be compatible with the reagents and reactions proposed. Such restrictions to the substituents which are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternate methods must then be used.

Compounds of Formula (I) of the present invention can be synthesized by the method of Scheme 1 comprising: step 1, an amino acid coupling; followed by step 2, a radical reduction; and an optional step 3, a reaction with R⁶-LG where LG is a leaving group, for example halide, mesylate, triflate or other leaving group well known to one skilled in the art. See Scheme 1. In the method of Scheme 1, step 1, a W—X—Y—Z-substituted aminolactam, XI, is coupled with an β-hydroxy acid X to form a lactam XII. The amine XI is coupled to an appropriately substituted carboxylic acid or acid chloride by methods well described in the literature for making amide bonds, for example, TBTU in DMF with a base, for example, NMM to give the elaborated compound XII. In step 2, the lactam XII is then reacted with thiocarbonyl diimidazole to form a carbonyl derivative XIII which is then converted to a compound of Formula (Ia′) by a radical hydride reduction. The deoxygenation of lactam XII to a

compound of Formula (Ia′) can be prepared by means of a free radical deoxygenation procedure [Barton and McCarobie, J. Chem Soc. Perkin Trans. 1, 1574 (1975); Robins et al., J. Am Chem. Soc. 103, 933 (1981); 105, 4059 (1983); Barton and Motherwell, Pure & Appl. Chem., 53, 15 (1981)]. This process entails the conversion of the free hydrdxy group in compound XII to a suitable derivative, for example, a thiono-ester XIII. Upon treatment with a hydrogen radical source in the presence of a radical initiator, compound XIII undergoes reductive deoxygenation to furnish compounds of general structure (Ia′). For such deoxygenation reactions, suitable sources of hydrogen radicals are the trialkyltin hydrides (e.g. tributyltin hydride) or tris (trialkylsilyl) silanes (e.g. (Me₃Si)₃SiH) [Schummer and Hofle, Syn. Lett. 106 (1990); Ballestri et al., J. Org. Chem 56, 678 (1991)], and suitable radical initiators are provided by azaisobutyronitrile (AIBN), heat, or irradiation. A compound of Formula (Ia′) can be alkylated using standard bases, for example LDA, NaH, or NaHMDS, to deprotonate the amide followed by addition of an alkylating agent with an appropriate leaving group (LG) for example halide, mesylate, or triflate, in an appropriate solvent to provide a compound of Formula (I′) with an R⁶ substituent.

Aldol derivatives X (Scheme 2) can be prepared by the procedure of Evans (D. A. Evans et al, Org. Synth. 1990, 68, 83-90). Acylation of an oxazolidinone XIV with an acid chloride provides acylated oxazolidinone XV. The reaction of XV with an aldehyde Q′CHO in the presence of dibutyl boron triflate gives an aldol product XVI. The chiral auxiliary of the aldol product XVI is then removed to give a β-hydroxy-carboxylic acid product X. Additional examples are found in D. A. Evans Aldrichimica Acta 1982, 15, 23-32. Alternative syntheses of compound X can be accomplished by the methods of Crimmins (M. T. Crimmins et al, J. Am. Chem. Soc. 1997, 119, 7883-7884), Paterson (I. Paterson et al, Org. React. 1997, 51, 1-200) and Mukaiyama (T. Mukaiyama et al, Org. React. 1994, 1-104).

Methods for the synthesis of lactams useful as intermediates in the synthesis of compounds as contemplated by the present invention in lactam ring B in Formula (I), including amino benzodiazepinones, amino dibenzoazepinones and other related heterocycles, are known in the art and are disclosed in a number of references including PCT publication number WO98/28268, WO99/66934, and WO00/07995, which are hereby incorporated by reference. Additional references include Bock, et al, J. Org. Chem., 1987, 52, 3232-3239; Sherrill et al, J. Org. Chem., 1995, 60, 730-734; and Walsh, D. A., Synthesis, September 1980, p. 677; and Brown, et. al., Tetrahedron Letters, 1971, 8, 667-670.

An example of an L-α-amino-β-thio-ε-caprolactam, as shown in Scheme 3, where ring B is the amino lactam of XVII and J is a sulfur atom has been reported in the literature. See S. A. Ahmed et al, FEBS Letters, (1984), vol. 174, pages 76-9. One skilled in the art can extend this methodology to the synthesis of β-amino and oxygen containing rings by analogy. The sulfur-containing molecules can also be oxidized to the sulfoxide and sulfone by methods known to one skilled in the art.

The WXYZ-substituted amino lactam XI can be formed by alkylation of an amino lactam with WXYZ-LG. For example in Scheme 4, the {tilde over (α)}-amine of compound XVIII can be protected with a BOC group. The protected {tilde over (α)}-amine XVIII of the {tilde over (α)}-amino-{tilde over (ε)}-caprolactam can be prepared by methods well known in the literature for amino protecting groups as discussed in Theodora W. Greene's book “Protective Groups in Organic Synthesis”, like N-Boc using di-t-butyldicarbonate in an appropriate solvent like DMSO. The lactam nitrogen of compound XV can be alkylated by generating the anion with bases such as LDA, lithium bis(trimethylsilyl)amide or sodium hydride in solvents like THF, with or without cosolvents such as DMPU or HMPA and reacting this with a variety of groups containing leaving groups (LG) like bromide, iodide, mesylate or tosylate. Alkylating agents such as α-bromo amides, ketones and acids can be prepared by a number of literature methods including halogenation of amino acids by diazotization or are commercially available. Other suitable alkylating agents such as alkyl, allylic and benzylic halides can be formed form a variety of precursors such as free-radical addition of halides or activation of alcohols, and other chemistries known to those skilled in the art. For discussion of these types of reactions, see Carey, F. A. and Sundberg, R. J., Advanced Organic Chemistry, Part A, New York: Plenum Press, 1990, pages 304-305, 342-347, 695-698. The N-Boc protecting group can be removed by any number of methods well known in the literature like TFA in methylene chloride to give the compound XIa.

An example of the method of Scheme 1 is illustrated in the preparation of compound 5 (Scheme 5). The aldol product 3 is obtained from an amino acid coupling of an β-hydroxyacid 1 and a benzodiazepine 2 using a standard coupling procedure. The coupled aldol product 3 is reacted with thiocarbonyl diimidazole in 1,2-dichloroethane to form a thiocarbamate 4. Reduction of thiocarbamate 4 with tri-n-butyltin hydride provides a benzodiazepine 5.

Alternatively, compounds of Formula (I) can be prepared according to Scheme 6. An acid XXI is coupled with a W—X—Y—Z-substituted aminolactam, XI, to give a compound of Formula (Ia) using methods commonly used in peptide syntheses, such as DCC, EDC, CDI, BOP, PyBOP, HATU, HBTU and phenyl ester mediated coupling, as described in A. R. Chamberlin, Chem. Rev. 1997, 97, 2243-2266. Subsequently, the amide nitrogen of compound (Ia) can optionally react with an R⁶-LG to give a compound of Formula (I).

An example of the method of Scheme 6 is illustrated in the preparation of compound 7 (Scheme 7). Carboxylic acid of formula 6 (commercially available) is coupled with 3-amino-1,4-benzodiazepin-2-one 2 (Sherrill and Sugg, J. Org. Chem 1995, 60, 730-734; Bock et al., J. Med. Chem., 1993, 36, 4276-4292) in the presence of EDC and HOBt to give compound 7 (S. Nozaki et al, Bull. Chem. Soc. Jpn. 1982, 55, 2165-2168). General methods for preparing compounds similar to compound 6 can be found in Evans, D. A., et al., J. Am. Chem. Soc. 1990, 112, 5290, Evans, D. A. Aldrichimica Acta 1982, 15, 23, and Ponpipom, M. M., Hagmann, W. K Tetrahedron 1999, 55, 6749.

Another example of the method of Scheme 6 is illustrated in the preparation of compound 12 (Scheme 8). In step 3′, a chiral lactic acid derivative 10 is coupled with 7-amino-6,7-dihydro-5-methyl-6-oxo-5H-dibenz[b,d]azepin 11 in the presence of HOBt and EDC to afford compound 12.

Compound 11 can be prepared by the methods describe in PCT patent application WO 99/32453. The chiral lactic acid derivative 10 is prepared from bis-alkylation of (2S)-2-hydroxy-4-methylpentanoic acid 8 with iodopentane to give the lactate 9 in step 1′. Subsequent hydrolysis of lactate 2 using LiOH in THF/H₂O affords the chiral lactic acid derivative 10 in step 2′. Alternatively, compound 10 and other similar chiral lactic acid derivatives can be prepared by the methods described in J. Org. Chem., 1986, 51, 2402, and Chem. Rev., 1992, 92, 919.

Aβ production has been implicated in the pathology of Alzheimer's Disease (AD). The compounds of the present invention have utility for the prevention and treatment of AD by inhibiting Aβ production. Methods of treatment target formation of Aβ production through the enzymes involved in the proteolytic processing of β amyloid precursor protein. Compounds that inhibit β or γ secretase activity, either directly or indirectly, control the production of Aβ. Such inhibition of β or γ secretases reduces production of Aβ and is expected to reduce or prevent the neurological disorders associated with Aβ protein, such as Alzheimer's Disease.

Cellular screening methods for inhibitors of Aβ production, testing methods for the in vivo suppression of Aβ production, and assays for the detection of secretase activity are known in the art and have been disclosed in numerous publications, including J. Med. Chem. 1999, 42, 3889-3898, PCT publication number WO 98/22493, EPO publication number 0652009, U.S. Pat. No. 5,703,129 and U.S. Pat. No. 5,593,846; all hereby incorporated by reference.

The compounds of the present invention have utility for the prevention and treatment of disorders involving Aβ production, such as cerebrovascular disorders.

Compounds of Formula (I) are expected to possess β-secretase inhibitory activity. The γ-secretase inhibitory activity of the compounds of the present invention is demonstrated using assays for such activity, for example, using the assay described below. Compounds of the present invention have been shown to inhibit the activity of γ-secretase, as determined by the Aβ immunoprecipitation assay.

Compounds provided by this invention should also be useful as standards and reagents in determining the ability of a potential pharmaceutical to inhibit A□ production. These would be provided in commercial kits comprising a compound of this invention.

As used herein “μg” denotes microgram, “mg” denotes milligram, “g” denotes gram, “μL” denotes microliter, “mL” denotes milliliter, “L” denotes liter, “nM” denotes nanomolar, “μM” denotes micromolar, “mM” denotes millimolar, “M” denotes molar, “nm” denotes nanometer, “SDS” denotes sodium dodecyl sulfate, and “DMSO” denotes dimethyl sulfoxide, and “EDTA” denotes ethylenediaminetetraacetic acid.

A compound is considered to be active if it has an IC₅₀ or K_(i) value of less than about 100 μM for the inhibition of Aβ production. Preferably the IC₅₀ or K_(i) value is less than about 10 μM; more preferably the IC₅₀ or K_(i) value is less than about 0.1 μM. Compounds of the present invention have been shown to inhibit Aβ protein production with an IC₅₀ or K_(i) value of less than 100 μM.

βAmyloid Precursor Protein Accumulation Assay

A novel assay to evaluate the accumulation of Aβ protein was developed to detect potential inhibitors of secretase. The assay uses the N 9 cell line, characterized for expression of exogenous APP by immunoblotting and immunoprecipitation.

The effect of test compounds on the accumulation of Aβ in the conditioned medium is tested by immunoprecipitation. Briefly, N 9 cells are grown to confluency in 6-well plates and washed twice with 1× Hank's buffered salt solution. The cells are starved in methionine/cysteine deficient media for 30 min, followed by replacement with fresh deficient media containing 150 uCi S35 Translabel (Amersham). Test compounds dissolved in DMSO (final concentration 1%) are added together with the addition of radiolabel. The cells are incubated for 4 h at 37° C. in a tissue culture incubator.

At the end of the incubation period, the conditioned medium is harvested and pre-cleared by the addition of 5 μl normal mouse serum and 50 ul of protein A Sepharose (Pharmacia), mixed by end-over-end rotation for 30 minutes at 4° C., followed by a brief centrifugation in a microfuge. The supernatant is then harvested and transferred to fresh tubes containing 5 ug of a monoclonal antibody (clone 1101.1; directed against an internal peptide sequence in Aβ) and 50 μl protein A Sepharose. After incubation overnight at 4° C., the samples are washed three times with high salt washing buffer (50 mM Tris, pH 7.5, 500 mM NaCl, 5 mM EDTA, 0.5% Nonidet P-40), three times with low salt wash buffer (50 mM Tris, pH 7.5, 150 mM NaCl, 5 mM EDTA, 0.5% Nonidet P-40), and three times with 10 mM Tris, pH 7.5. The pellet after the last wash is resuspended in SDS sample buffer (Laemmli, 1970) and boiled for 3 minutes. The supernatant is then fractionated on either 10-20% Tris/Tricine SDS gels or on 16.5% Tris/Tricine SDS gels. The gels are dried and exposed to X-ray film or analyzed by phosphorimaging. The resulting image is analyzed for the presence of Aβ polypeptides. The steady-state level of Aβ in the presence of a test compound is compared to wells treated with DMSO (1%) alone. A typical test compound blocks Aβ accumulation in the conditioned medium, and is therefore considered active, with an IC₅₀ less than 100 μM.

C-Terminus β Amyloid Precursor Protein Accumulation Assay

The effect of test compounds on the accumulation of C-terminal fragments is determined by immunoprecipitation of APP and fragments thereof from cell lysates. N 9 cells are metabolically labeled as above in the presence or absence of test compounds. At the end of the incubation period, the conditioned medium are harvested and cells lysed in RIPA buffer (10 mM Tris, pH 8.0 containing 1% Triton X-100, 1% deoxycholate, 0.1% SDS, 150 mM NaCl, 0.125% NaN₃). Again, lysates are precleared with 5 ul normal rabbit serum/50 μl protein A Sepharose, followed by the addition of BC-1 antiserum (15 μl;) and 50 μl protein A Sepharose for 16 hours at 4° C. The immunoprecipitates are washed as above, bound proteins eluted by boiling in SDS sample buffer and fractionated by Tris/Tricine SDS-PAGE. After exposure to X-ray film or phosphorimager, the resulting images are analyzed for the presence of C-terminal APP fragments. The steady-state level of C-terminal APP fragments is compared to wells treated with DMSO (1%) alone. A typical test compound stimulates C-terminal fragment accumulation in the cell lysates, and is therefore considered active, with an IC₅₀ less than 100 μM.

Aβ Immunoprecipitation Assay

This immunoprecipitation assay is specific for γ secretase (i.e., proteolytic activity required to generate the C-terminal end of Aβ either by direct cleavage or generating a C-terminal extended species which is subsequently further proteolyzed). N 9 cells are pulse labeled in the presence of a reported γ secretase inhibitor (MDL 28170) for 1 h, followed by washing to remove radiolabel and MDL 28170. The media is replaced and test compounds are added. The cells are chased for increasing periods of times and Aβ is isolated from the conditioned medium and C-terminal fragments from cell lysates (see above). The test compounds are characterized whether a stabilization of C-terminal fragments is observed and whether Aβ is generated from these accumulated precursor. A typical test compound prevents the generation of Aβ out of accumulated C-terminal fragments and is considered active with an IC₅₀ less than 100 μM.
